CHlMNEY-COWL.

, SPECIFICATION forming part of Letters Patent No. 320,815, dated June 1885- Application filed April 23, 1885.

To aZZ whom it may concern: 7

Be it known that we, GEORGE W. PowERs, JAMES H. JONES, and J AMES M. PowERs, citizens of the United States of America, residing at Streator, in the county of La Salle and State of Illinois, have invented certain new and useful Improvements in Ohimney-Oowls; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form apart of this specification.

Our invention relates to certain new and useful improvements in rotary chimney-cowls; and it consists in the construction and combination of the parts, as will be hereinafter fully set forth, and specifically pointed out in the claims.

In the accompanying drawings, which illustrate our invention, Figure 1 is a perspective view, and Fig. 2 is a sectional view.

A represents an annular rim, which is provided with a flange, a, which projects from its upper edge and forms a rest for the annular rim A when placed in position inside of a chimney. The rim A is also provided with a series of openings or perforations for the passage of bolts or rivets for securing the rim to the upper end of the pipe which is located within the chimney.

The annular rim A is provided with two or more inwardly-extending arms, A, which terminate at the center, where they are united to each other and provided with a central bearing for a vertical shaft. The hood is made from a single piece of metal, which is stamped into shape, a V-shaped portion being first removed from the blank at its upper end, so that it can be shaped as shown in Fig. 1.

A vane, O, is attached to and braced by means of the rods 0 O, the ends of which are riveted to the upper portion of the vane and to the upper portion of the rotary hood.

To the inner side of the hood 0 is attached a depending socket, D, which forms a bearing for the upper end of the rod E. A bracket having a bent portion, f, which extends at right angles with the rod E, is secured to the lower portion of the hood by means of bolts (No model.)

ec, which pass through the hood and also through slots in the bent end of the bracket F. It will be readily seen by adjusting the bracket upwardly the lower end of the hood will be thrown away from the ring or rim A, while the movement in an opposite direction will bring the end nearer the rim.

The rod E is provided with a collar, G, which is located above the horizontal portion of the bracket and will prevent the withdrawal of said bar from the socket D. This bar E is screw-threaded at its opposite end,

and is rigidly secured to the bearing at the ends of the arms A by means of nutsg g.

It will be readily seen that the cowl is of such construction that it will protect the top of the chimney and turn so as to present the convex surface to the wind, thereby deflecting the wind over the top and sides of the chimney.

We are aware of the construction set forth and disclosed in the United States Patent to Hess, No. 243,133, dated June 21, 1881, and Gordemen, N 0. 142,909, September 16, 1873, and we therefore do not claim, broadly, any features disclosed by said patents.

\Ve claim- 1. The combination, in a rotary chimneycowl, of a stationary spindle having a flange thereon, a cone or shield, a bracket slotted as described, bolts passing through said slots and engaging said cone, and a socket, the parts being combined, substantiallyas set forth.

2. In a rotary chimney-cowl, a revolving pyramidical-shaped cone provided with a depending socket and a vane, G, and adjustable bracket F, with perforated ends, and a stationary spindle having a flange, G, screwthreaded end, and securing-nuts g, in combination with the annular flanged rim with inwardly-projecting arms which form a bearing for the spindle, the parts being organized substantially as shown, and for the purpose set forth.

In testimony whereof we aflix our signatures in presence of two witnesses.

GEORGE W. POWERS. JAMES HERBERT JONES. JAMES M. POWERS.
